Yes Ed I dig all summer and we have some on hand most of the summer. We live just around the corner from you in Fairhaven Ma. One of my customers has a place on the Westport River so I get a license to dig there.
I vacuum seal and freeze batches of 70 little necks and the juices from cooking them to use for chowder in the winter months.
Never been to Prudence Island but use to get invited every fall to bow hunt a friends land there but never had the time back then.
Do love the island life though as most of my summers as a child were spent on Nashawena Island off the coast and then on Cuttyhunk.
